In today's demonstration, the Objet Connex 3D printer has created a keyboard replica. The amazing part about this particular print job is that the keys didn't have to be printed separately and inserted into the keyboard. Everything was created in a single print, further demonstrating the power of Objet's Connex line of 3D printers.
Of course, these keyboards can't actually connect to a PC as they are only plastic prototypes. Real keyboards will have to be produced via traditional means until 3D printers can start creating circuitry. Until then, we're left with a promising, but currently useless, tech demo of what's to come in the world of 3D printing.
